The incidence rate of preeclampsia was 3.6%, and that of IGR was 9%. Preeclampsia occurred in 4.3% of patients in the corresponding risk group, IGR, in 11.6%, respectively. In 31.2% of women with IGR, low risks were calculated for IGR, and high risks for PE. However, the established risk of IGR is associated with an increase in the frequency of spontaneous miscarriage in the observed group. In the group of calculated high risk for PR, this complication did not occur in any case, while in other risk groups (IGR and PE), premature births were observed in 5.3% of cases.</p> <p><bold>Conclusion. </bold>The first trimester screening generally accepted in the Russian Federation is quite inaccurate in terms of risk prediction. The obtained characteristics of the effectiveness of this study suggest the inevitability of revising approaches to first trimester screening and replacing the studied biomarkers. In the group we observed, patients who subsequently experienced spontaneous miscarriage had significantly increased risks of IGR. This fact should be verified on a larger sample of patients with such an unfavorable pregnancy outcome, which requires further research in this area.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – оценить результативность скрининга первого триместра в отношении прогноза больших акушерских синдромов – преэклампсии (ПЭ), задержки роста плода (ЗРП) и преждевременных родов (ПР).</p> <p><bold>Материал и методы. </bold>Нами были проанализированы результаты скрининга первого триместра и исходы беременности у 992 пациенток, входящих в группы риска по развитию ПЭ, ЗРП и ПР согласно программе Astrae.</p> <p><bold>Результаты. </bold>ПЭ лидирует по числу рассчитанных рисков, как изолированно (47,4%), так и в сочетании с ЗРП (27,6%). У 75,4% женщин не реализовалась вероятность того или иного осложнения беременности, несмотря на то что они были отнесены в группу риска по результатам скрининга. Частота встречаемости ПЭ составила 3,6%, а ЗРП – 9%. Преэклампсия реализовалась у 4,3% пациенток соответствующей группы риска, ЗРП – у 11,6% соответственно. У 31,2% женщин с реализовавшейся ЗРП были рассчитаны низкие риски в отношении ЗРП и высокие для ПЭ. Однако установленный риск ЗРП ассоциирован с увеличением частоты самопроизвольного выкидыша у наблюдаемой группы. В группе рассчитанного высокого риска по ПР данное осложнение не реализовалось ни в одном случае, тогда как по в других группах риска (ЗРП и ПЭ) преждевременные роды наблюдались в 5,3% случаев.</p> <p><bold>Заключение. </bold>В отношении прогноза рисков общепринятый в РФ скрининг первого триместра является довольно неточным. Полученные характеристики результативности данного исследования свидетельствуют о необходимости пересмотра подходов к проведению скрининга первого триместра и замене исследуемых биомаркеров. В наблюдаемой нами группе пациенток, у которых впоследствии произошел самопроизвольный выкидыш, были достоверно повышенные риски ЗРП. Данный факт требует проверки на более крупной выборке пациенток с таким неблагоприятным исходом беременности и дальнейших исследований в этом направлении.</p></trans-abstract><kwd-group xml:lang="en"><kwd>first trimester screening</kwd><kwd>Astrae</kwd><kwd>preeclampsia</kwd><kwd>IGR</kwd><kwd>preterm labor</kwd><kwd>late miscarriage</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>скрининг первого триместра</kwd><kwd>Astrae</kwd><kwd>преэклампсия</kwd><kwd>ЗРП</kwd><kwd>преждевременные роды</kwd><kwd>поздний выкидыш</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Park H, Shim S, Cha D.
